A bisoprolol-containing adhesive patch which comprises a support and an adhesive layer superposed on one side thereof. The adhesive layer is characterized by comprising a branched C12-28 monohydric alcohol, a free bisoprolol base, and a polyisobutylene-based pressure-sensitive adhesive. In this constitution, the compatibility between the polyisobutylene-based pressure-sensitive adhesive and the free bisoprolol base can be specifically heightened. As a result, it is possible to incorporate the free bisoprolol base in a large amount. The pressure-sensitive adhesive layer can be inhibited from suffering the bleeding of the free bisoprolol base and have practically sufficient pressure-sensitive adhesive properties.
